T0 all whom it may concern:

Be it known that we, THOMAS CORSOADEN and FRANKLIN HOLLAND, citizens ofthe United States, residing at NeWBritain, in the county of Hartford andState of Connecticut, have invented certain new and useful Improvementsin Antifriction-Hinges, of which the following is a specification.

Our invention relates to improvements in anti-friction hinges, and thechief object of4 our improvement is to provide a cheap and eflicient Wayof securing the anti-friction devices to the leaves of the hinge. K

In the accompanying drawings: Figure 1 is` a front elevation of a hingeconstructed in accordance with our improvement. Fig. 2 a verticalsection of one of the knuckles of said hinge on the line a; of Fig. l,together with an elevation of a portion of the hinge pintle andanti-friction devices secured to said knuckle. Fig. 3 is a like view ofthe same in a hinge having a plain knuckle. Fig 4 is a detached verticalsection of the attaching sleeve for the anti-friction devices, and Fig.

5 is a like sectional view of the sleeve in itsY final form.

A A designate the leaves of the hinge which may be of any'ordinaryconstruction. As

shown in the drawings, it is a wroughtiron hinge with its knuckles 5 and6l corrugated or beaded, but our invention is applicable'to ordinaryhinges having plain knuckles.

7 designates anti-friction devices whichl consist essentially of twowashers, either withor without an inclosed washer, rollers, balls, orother anti-,friction devices. l cient space is left between part of theknuckles 5 and 6 to insertrthese anti-friction devices particular hingeshown.

A suffi! which is inserted within this chamber 8 and enlarged at its endso-as to secure it to the 5o `end'of the knuckle as shown in Figs. 2 and3, even though the pintle 9 be removed.

.- InFigs. l andv 2 the chamber 8 is formed Within the hollow of one ofthe beads or corrugations, but this is only incidental to the Anoverhanging chamber can be readily formed in the knuckle of anyordinaryV hinge, as for example, the chamber 8S in the plain knuckle 55as shown inF-ig. 3, the anti-friction devices being se- 6o cured thereinin the same manner.

In order to assemble the parts, we first form the projecting end of thissleeve 10 with cylindrical sides on its exterior, while the excess ofmetal is upon the inside as shown in 6 5 the detached sleeve, Fig. l.This sleeve is\4 long enough to pass through both of the antifrictionwashers and is preferably provided with a head 1l which is let into theouter side of the outer washer, but it is evident that if '7o desiredthis sleeve might be made integral with the outer washer. After thesleeve has been formed as shown in Fig. 4, the anti-friction devices areplaced together on said sleeve .and its projecting endis placed withinthe vchamber 8 or 88. A pin or punch is'then driven 'through the sleeveso as to `forcev` the` excess of metal Ewhich is upon theinside of Y thesleeve outwardly and form -the enlarged end as shown in Figs. 2, 3 and15, thereby changing 8o the' metal at the projecting endof the sleevefrom the form shown in Fig. ttothat shown in Fig. v5- in Whichtheexces'sof metal is thrown from the inside ofgthesleeve to the outsideasshown, and theanti-friction devicesJthereby secured in g-"plac`e sothat they willnot be accidentally. detached from the hinge leaves.

Other means may be devised for assembling the parts, but the foregoingare thebest go means known to us for'assembling a holding sleeve havingan enlarged end within a chamber having overhangingside walls.

By our improvements, we are enabled to cheaply and conveniently securethe anti-friction devices to the ends of` such knucklesas may be desiredand in such a manner that and having its end enlarged fol` holflng theto theywill not be liable to accidental detachparts in pleceubstantiallyas descmbed and ment. for the purpose specified.
